The centralized integrated database concept is very useful to
design at various stages. During the creation of a geometric model,
any changes made to the model in any view are reflected on the
model database. The effects of these changes are also reflected on
the analysis results. Consider, for example, the effect of some
dimensions on mass properties of a model. The designer would change
any relevant dimension and calculate the mass properties of the
model with one command. This cycle of change/calculate can be
repeated as many times as needed. If conventional or manual
alternatives were to be used, they would be too inconvenient and
slow to deter the designer from attempting many design
alternatives. This same discussion can apply to engineering
analysis, such as finite elements, mechanisms, heat transfer, fluid
mechanics, etc.
